Because he can!

The legs may shake if the dog is frightened.
Shake hands.
I think you should take your dog to your veterinarian, particularly if your dog's legs only shake or tremble when he is going from standing to lying down. This could be a symptom of nerve damage or muscle weakness, which needs to be diagnosed and potentially treated before it gets worse.
All dogs have dew claws on their front legs (unless they are removed) and some dogs may also have them on their back legs. This is not affected by gender.
Male dogs always do; female dogs usually croutch down on their rear legs but can also pee while standing if necessary.
According to Bennie Hill, shake hands.
